No dice . . . same error message on the still camera, same disappearing act on the video camera. Any other suggestions? (Similar complaints from previous years which I've found while searching this forum suggest downloading the latest operating system -- but I think the Blackberry Desktop Manager automatically looks for updates every time I synch. Other suggested solutions from those previous years said to select "Close" from the menu of all applications, which I did, and to remove any recently-downloaded applications, which I also did.)
